Struct PerfScope 

pub struct PerfScope {
    start: u64,
    accumulator: &'static AtomicU64,
    counter: &'static AtomicU64,
}

Measures elapsed TSC cycles between construction and drop, accumulating into the given counter pair.

Usage:

let _perf = PerfScope::new(&IRQ_TIMER_TSC, &IRQ_TIMER_COUNT);
// ... measured code ...
// counters updated on drop

Fields

start: u64

accumulator: &'static AtomicU64

counter: &'static AtomicU64

Implementations

impl PerfScope

pub fn new(accumulator: &'static AtomicU64, counter: &'static AtomicU64) -> Self

Trait Implementations

impl Drop for PerfScope

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
